UNITED STATES PATENT OE IcE.
LAURENS KENT, OF DORSET, VERMONT.
IMPROVEMENT IN THE MODE OF EXTRACTING COLOR FROM DYE-WOODS.
Specification forming part of Letters Patent No. 951, dated September 27, 1838.
To all whom it may concern:
Be it known that I, LAURENS KENT, of Dorset, in the county of Bennington and State ot Vermont, haveinvented a new and improved mode of extracting the color from dye-Woods by steam or distillation, reducing the same to a gum or powder; and I do hereby declare that the following is a full and exact description.
The nature of my invention consists in extracting the color from dye-woods, reducing the same'to a gum or powder in a pure state and in greater quantities than can be produced in the common way of boiling.
To enable others skilled in the art to make and use my invention, I will proceed to describe its construction and operation.
I construct my steamer or tub sufficiently large to contain four or five hundred pounds of ground wood, the tub standing on the end. Eightinches from thebottomlfixalinestrainer. The tub above the strainer is then filled and made perfectly tight. Through the center of the head I enter my steam-pipe from the boiler or still, which is brass or copper. The steam condenses in the wood, and leaehes into the space below thestrainer strong liquor. This is drawn otftf and putagain into the boiler, and the water or liquor run off again into the wood, as before, leaving the coloring substance in the boiler, which is taken out and dried. As the color or gum of some dye-woods cannot be extracted perfectly with water, I make use of al- LAUEENs KENT. [L. s.]
